Q

Catecholamines decrease which of the following immune system cells during acute and chronic stress?

a. Macrophages
b. Natural Killer Cells
c. B Lymphocytes
d. T Lymphocytes

A

B

Pg 345 table 11-2 ‘Physiologic Effects of Catecholamines’ under ‘lymphoid tissue’ it states “acute and chronic stress inhibits several components of innate immunity, particularly decreasing number of natural killer cells.” As I was reading page 346, the paragraph you cited, it does talk about a transient, short term (approx 2 hour) elevation of NK cells after an acute elevation of catecholamine levels, and gives the example of injection with epinephrine in healthy subjects. So I have read in the literature to see exactly what this discrepancy is about and found that there appears to be other references that support a very short elevation in NK cells from 1-2 hours after a stressor, followed by a subsequent decrease in longterm NK levels. So this question would be more accurate in a chronic stress situation, there would be a decrease in NK cells.
